چکیده

The increased demand of the world for energy and its reliance on fossil fuels ultimately contribute to the surge in the levels of carbon dioxide in the atmosphere. To achieve a green efficient carbon capture, a novel multi-component amine-amino acid solvent including methyldiethanolamine (MDEA), diisopropanolamine (DIPA), and Arginine (ARG) was designated for CO2 absorption in a T-microreactor. To assess the potential absorption of aqueous solutions of the desired mixed amines, the CO2 absorption percentage (AP) and the total volumetric gas-phase mass transfer coefficient (TGMTC) were investigated over a wide range of gas flow rate (60-240 mL/min), solvent flow rate (2-6 mL/min), at three MDEA:DIPA:ARG mixing concentrations of (28:8:4), (28:6:6), and (28:4:8)) wt%. The research findings demonstrate an increment of 31% in CO2 absorption percentage by reducing DIPA to 4 wt% and rising the arginine concentration to 8 wt% in ternary amine solutions. Additionally, the highest mass transfer coefficient was achieved 38.06 (kmol/m3.h.kPa) utilizing the aqueous mixture of MDEA+DIPA+ARG (28+4+8) wt%.
